We divide 397737 by 20
Our goal is to divide 397737 by 20.

Moving on to step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 20

On to step 2:
20 goes into 39 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 19 after subtracting 20 from 39.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 20

Advancing to step 3:
20 can be fit into 197 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 180 from 197 to get 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 20

Step 4:
20 goes into 177 8 times with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 198.0
The remainder is 17 after subtracting 160 from 177.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 20

Going ahead to step 5:
When dividing 173 by 20, we get 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 1988.0
If we take 160 away from 173, we end up with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 20

Moving on to step 6:
137 divided by 20 is 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 19886.0
Subtract 120 from 137 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
170 divided by 20 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 19886.8
Subtract 160 from 170 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 19886.85
If we take 100 away from 100, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 19886.85
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19886.85
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 19886.85 and a remainder of 0.0.
